The phrase "a more precise assay" is correct and usable in written English.
It can be used when discussing the accuracy or specificity of a test or measurement, particularly in scientific or medical contexts.
Example: "In our study, we aim to develop a more precise assay to detect the presence of the virus in patients."
Alternatives: "a more accurate test" or "a more exact measurement."
An alternative strategy to more specifically probe Sec body function would be to use a more precise assay.
In addition, 25(OH D measurements were performed using mass spectroscopy, a more precise assay compared to other techniques [ 16, 25].
DOI: http://dx.doi.org/10.7554/eLife.06085.014 Delay eyeblink conditioning is a more precise assay of cerebellar function than two phenotypes that are commonly assumed to measure cerebellar function, rotarod and gait.
In addition and/or alternatively, reviewer 2 suggests that more precise assays should be used to test your model that Sec bodies are required to re-build the secretory pathway during recovery from starvation.
This assay enables a more precise measurement of copeptin, which could also explain in part the differences in the "rule-out" studies.
The 4-PL function fits these data with a high degree of accuracy and extends the range of the assay, thus providing a more precise measurement of antibody concentration for patient sera (10).
Herein, the binding affinities of the three recombinant cytosolic AtACBPs to acyl-CoA esters were investigated by ITC (isothermal titration calorimetry), which represents a more precise method to measure protein ligand binding compared with Lipidex assays [ 40].
A more precise diagnosis may be made with a C-serotonin release assay, but this test is not routinely available in most clinical settings [ 26].
Furthermore, in vitro binding assays will not provide any structural details about the interaction, but will merely provide a more precise estimate of binding affinities.
